Description

The utility model relates to railway tanks for the transport of hardened products and can be used in stationary tanks, tankers and containers.

A well-known wagon is a tank for hardening products, which includes a platform with an insulated boiler installed on it, equipped with devices for draining and filling the product, a heat exchanger in the form of a shirt covering the lower part of the boiler (RU No. 2063916, B65D 88/74, 07.20.1996).

The heat exchange device located in the lower part of the boiler does not provide for the heating of the drain pipe and the unions of the drain devices located in the upper part of the boiler hatch, which increases the heating time of the product.

A tank car is known for transporting, for example, pitch, including a heat-insulated boiler installed on the platform, with drain and loading devices located in the boiler hatch, a boiler heating system in the form of an air gap between the boiler and insulation on the entire surface of the boiler, except for the hatch with installed devices discharge and filling, with tubular electric heaters (TENs) installed in the lower part of the air gap (SU No. 706271, B61D 5/04, 12/31/1979 - taken as a prototype).

one

The disadvantage of this tank car is the lack of heating of the drain pipe and the installation area of the unions of the drain and liquid filling devices. Due to the lack of direct contact with the coolant, the product in the drain pipe heats up after warming up the bulk of the product covering the pipe. The fittings are heated only by heating the air space in the hatch, which is ineffective.

The absence of heating in the installation area of the fittings and the drain pipe directly with the coolant circulating in the boiler heating system increases the total product heating time and, as a result, the tank idle time under unloading.

The task is achieved in that the installation area of the fittings for product drainage devices and the drain pipe are equipped with chambers connected by channels to the boiler heating system.

The chimney heating chamber is made in the form of a shell connecting two surfaces through which the nozzle pipes pass, one of the surfaces is a boiler shell, and windows connecting the chamber with channels to the boiler heating system are made in the lower part of the shell.

The drain pipe heating chamber is made in the form of a jacket, covering it with a gap, in the lower part it is connected hermetically with the pipe, in the upper part it is connected to the nozzle heating chamber, in the surface of which there are windows in the area between the jacket and the pipe, in the lower part the jacket is connected with cavity of the boiler heating system.

The utility model is illustrated by images where

in FIG. 1 shows a General view of the tank car;

in FIG. 2 is a section “A-A” in FIG. one;

in FIG. 3 - remote element "B" in FIG. one.

The proposed tank car for hardening products, including a thermally insulated boiler 1, mounted on a platform 2

with a heating device 3 in the form of a shell covering the boiler body or part thereof and forming, together with the walls of the boiler, a cavity with a circulating coolant. In the lower part of the cavity, heat electric heaters 5 (heating elements) are installed. To reduce heat loss, the boiler is protected by thermal insulation 4. In the hatch 7 there are fittings 6 for installation of loading and unloading devices. The heating chamber 8 of the fittings consists of a shell 9 connecting the upper 10 and lower 11 surfaces. In the lower part of the shell 9, windows 12 are made connecting the chamber through channels 13 with the heating device 3 of the boiler. The heating chamber of the drain pipe is made in the form of a jacket 14, in the upper part it is connected to the heating chamber 8, the windows 15 are made in the chamber surface 11, the jacket 14 is connected hermetically to the drain pipe 16 in the lower part. The shirt 14 is connected through channels 18 through the windows 17 made in it with the help of windows made in the boiler shell, with its heating device.

When loading and unloading the product, the boiler can change its shape, which leads to a change in the distance from the lower end of the drain pipe to the boiler surface, and this change negatively affects the size and position of the channels connecting the drain pipe heating chambers to the boiler heating system. Also, a negative effect on the size and position of the channels has a change in temperature when the product is heated. Therefore, in order to eliminate negative factors on the channels connecting the drain pipe heating chamber to the boiler heating device, the channels are equipped with special compensators 19, for example, bellows ones.

The heat exchange system of the tank car for hardening products, including the boiler heating device, made in the form of an air gap between the boiler and the insulation, in the lower part of which there are heating elements, heating chambers of the fitting installation zones

the boiler and the drain pipe, connected by channels between each other and with the heating device of the boiler, operates as follows.

Heating elements connected to an external source of electricity heat the air located in the air cavity, which begins to circulate in this cavity as the temperature rises.

Due to the presence of channels between the chambers and the boiler heating device, the air, when heated, circulates simultaneously in the entire space of the heat exchange system. The provided chambers for heating the fittings and the drain pipe and connecting them with channels to the heating device of the boiler increase the heating area of the product located in the boiler, and therefore increase the heat transfer to the product in the boiler, which reduces the heating time of the product and the downtime of the tank car under unloading.

In the manufacture of heating chambers for fittings and a drain pipe, it is not necessary to create new materials, unique technological equipment and equipment, as well as manufacturing methods.
